Is Microsoft pricing itself out of the world computer market?

When Microsoft's Vista comes out late next year or early 2007 you'll need a 3.0 GHz CPU with lots of other energy loving parts. But based on the story about Ghana in Africa because of their weather conditions they can only use 386s and 486s. Why? Because the heat generated from the new CPUs (and I have an AMD 64 3200+) would probably be too hot in that heat.

Open Source will probably be the slow death of Microsoft, or could it possibly increase global warming because of the energy needs of new computers and operating systems? Is that why Intel has started it's power per watt marketing and technology strategy in order to cool Microsoft down a bit? We'll give it some time to get the answer.
